Married for 20 years, Yumi finally bought her own home and was living a smooth life with her husband and daughter. However, after just two weeks, her husband was transferred and moved away from his family. Unable to contain her frustration, Yumi complained to her part-time coworker, university student Yuki. Having just moved and not knowing what to do, Yuki had always been kind to her. At the time, Yumi did not know yet what Yuki's feelings were, what Yuki's intentions were, and that she would never be able to return to being her husband, to being a man.
